SHINGLE-MACHIN E.

Specification of Letters Patent.

Patented Dec. 29, 1908.

To all whom it may concern:

Be it known that I, ABRAHAM L. ENGLISH, a citizen of the United States of America, and a resident of the city of Everett, in the county of Snohomish and State of Washington, have invented certain new and useful Improvements in Shingle-Machines, of which the following is a specification.

The present invention relates to certain new and useful improvements in horizontal shingle machines, aiming primarily to provide a machine of this type in which shingles can be cut in anefficient manner from a block carried on a reciprocating carriage.

With the above and other desirable obj ects in view, to be referred to as the descri tion progresses, the invention resides in t e features of construction, arrangement and combination of parts, hereinafter described and succinctly defined in the annexed claims.

In the accompanying drawings, forming a part of this specification, and in which like reference numerals indicate like parts throughout the several views: Figure 1 is a view in top plan of a shingle machine constructed in accordance with my invention, parts being broken away. Fig. 2 is a section taken on line 22 of Fig. 1. Fig. 3 is a plan view of the carriage removed, on large scale, I parts being shown in section, and Fig. 4 1s a section taken on line 44 of Fig. 3.

Reference numeral 1 indicates the frame of the shingle machine, which as now considered, is provided with a stand 2 on which, at opposite sides of frame 1, are journaled shafts 3. These shafts are provided with.

rollers 4, over which the band saw 5 passes. 6 indicates the carriage for feeding the bolt to the saw, said carriage being mounted for reciprocation on suitable tracks 7, and being connected by a pitman 8 to the driving mechanism. This "driving mechanism comprises a disk 9, fixed to a drive shaft 10, and provided with a pin 11 which rides in a slot 11, of an arm 12, pivoted at its lower portion, as at 13, to frame 1. 'Pitman 8 is guided between rollers 14, and is pivotally connected to the free end portion of arm 12 by a pin 15 which rides in a slot 15 of said arm, as clearly illustrated in Figs. 1 and 2.

Carriage 6, on its sides, is provided with outwardly projecting frames 6, which embrace the tracks 7 so as to slidably support the carriage thereon, and in saidv frames .6 are mounted suitable anti-friction rollers 6" the bolt to the saw for cutting in both directions, saw 5 being provided on each edge with teeth as clearly shown, and therefore tracks 7 are alternately tilted to relatively reversely inclined positions. To effect this operation, I provide, on frame 1, horizontally disposed rock shafts, 17, arranged laterally of the tracks beneath the end portions thereof, which shafts are provided with cams 18, each engaged with the underface of the adjacent overlying track. Cranks 19, fixed to shafts 17 are connected by a link 20, whereby the said shafts are moved in unison to elevate the cams 18 .of one shaft and lower the cams of the other, thereby adjusting tracks 7 Shafts 17 are provided with laterally projecting parts 21 adapted to be engaged y arms 22, secured to carriage 6, to effect the rocking of said shafts.-

Reference numeral 23 indicates the shingle bolt frame which is pivotally supported on carriage 6 on a pin 24, so that 1t can be swung to oblique positions relatively to the path of travel of the saw, as desired, whereby the shingle bolt can be presented to the saw with one edge portion thereof foremost. This shingle bolt frame is swung to relatively reverse diagonal positions, by an arm 25 which is slidable in a bracket 27 of frame 1 and has lugs '26, 26 adapted to alternately strike said bracket and hold said arm while the carriage moves onward to the end of its stroke. The shingle bolt frame is held against accidental movement by suitable means, as 28, in the form of a bar having its ends pointed and engaged, one in an aperture of 2. lug 29 on frame 23, and the other in an aperture of a spring metal plate 30, secure to carriage 6. Bar 28, is normally in an inclined position as shown, and when the shingle bolt frame is swung from the position shown in I ig. 1, as when the work is to be fed into the other side of the saw, spring plate 30,upon being depressed by bar 28 permits of the same being swung to a relatively reverse inclined position as indicated by dotted lines in l ig. 1. The resistance offered by said spring plate is, however, suilicient to, in conjunction with bar 28, hold the shingle bolt frame securely in position, when adjtsted. Arm 25 is connected to the shingle bolt frame by a pin 25 which passes through a slot 31 in one side of carriage 6.

Shingle bolt frame 23, is provided with clamps 32, 32, preferably arranged at oppo site sides thereof, the former as now consid ered, being fixed and the latter of which there are several, being yieldingly held in operative position. Llamps 32 are arranged side by side with their roughened gripping ortions 33 arranged well within the shingle olt frame, while the shanls or bodies of said clamps are arranged in the side of said shingle bolt frame. At their inner ends, clamps 32 are cut out for reception of arms 34, formed with slots 35 in which pins 36, car ried by the clamps, are received. Arms 34 are loosely mounted on a fixed shaft 37, and are engaged ty springs 38 held under tension to exert presspre to constantly tend to throw said arms forward, said springs being S601 red at one end to adji stable collars 39, and at their other ends to said arms. By this con struction, clamps 32 being yieldingly pressed outwardly, independent action thereof is permitted in compensating for unevenness in the side of the shingle bolt.

Reference niimeral 40, indicates an equalizer bar, slidably mounted in the side of the shingle bolt frame at the outer side of shaft 37, and connected to clamps 32 by links 41. The connection, between said links and said clamps consisting of pins 42, riding in slots 43 of said links to allow for the independent movement of said clamps, as previously de scribed.

Connected to equalizing bar 40, by links 44, are a pair of arms 45, pivoted at 46 to carriage 6 and projecting therefrom in opposite directions and formed with curved cam extensions which, as the carriage reaches the end of its travel, strikes rollers 47, carried by frame 1, and in moving by said rollers, said curved cam extensions are forced inward, thereby drawing outward the equalizing bar 40 and the clamps 32 so as to release the shingle bolt to allow it to fall onto one of the underlying tables 48, 48 where it is set prior to its being reclamped for travel with the carriage on its return stroke. Tables 48, 48 are of ordinary construction, comprising opposite sections hinged together by pins 49 and having at their free ends rests 50 for the shingle bolt.

On the pins 49 are mounted sleeves 51 to which vertical supports 52 are fixed, said suplports extending downwardly and engaged Wit suitable frame parts, whereby the respective tables are secured in position. Table 48 is secured in a laterally extending bar 53 of frame 1 while table 48 has its depending support slidably mounted in a sni able stand 54. I slidably support the said depending support of this table to effect an adjustment thereof in order that the shingle bolt can be properly positioned for a prime. ry or trimming cut, such adjtstment being effected by a lever 55 pivoted to said dependent support and to the stand 54 and haying its free end engaged with. spitable teeth 50. After the trimming out has been produced table 48 is reset to its normal position.

By feeding the shingle bolt to the saw in a diagonal position, as described, the mt is started in the forward edge of the shingle bolt. Therefore the saw will crt across the grain of the wood, and the saw d'i st thi produced will readily break and fall from the out, as contradistin 'i ished from the clogging action of the curled shavings, prodrced by a saw cutting with the grain of the wood, as found in machines where the saw is broi ght up against the forward face of the. shingle bolt, thereby preventing btrning of the saw.

Having thus filly described my invention, what I claim as new and desire to seerre by Letters Patent of the United States, is:

1. In a machine of the character described, a frame, a carriage s. pported thereon for reciprocation, a saw for operating on the work conveyed during both strokes of said carriage, a shingle bolt frame supported on said carriage for movement to (,liagonal positions, and means for operating said shingle bolt frame to a relatively reverse diagonal position as the carriage reaches each end of its stroke.
